4GAS-HEATED IRON.

SPECIFICATION forlrling` part of Letters Patent N 0. 699,683, dated May13, 1902. Application filed December 18, 1901. Serial No. 86,344. (Nomodel.)

To all whom t may concern.-

Be it known that I, BENJAMIN N. I-IAwns, a citizen of the United States,residing in the city of Washington, District of Columbia, have inventedcertain new and useful Improvements in Gas-Heated Irons; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the artto which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to new and useful4 improvements in gas-heatedflat-irons.

The primary object of the invention is to provide an iron of simpleconstruction in which the gas will be ymixed with the air in such a waythat perfect combustion will be effected and the maximum amount of heatobtained with economical use of gas.

A further object of the invention is to provide an iron in which theburner canbe readily adjusted vertically within the body of the iron toadapt said iron to the different gaspressures and in which the necessaryheating capacity under all conditions likely to oceur will be providedfor..

Other objects and advantages looking to the general improvement of ironsof this character will become apparent in the course of the followingdescription, and the points of novelty will be set forth in the claims.

In the drawings illustrating my invention, Figure 1 is a perspectiveview of the iron complete. Fig. 2 is a central longitudinal sectionthereof. Fig. 3 is a transverse section taken about on the line :c ofFig. 2. Fig. 4 is a detail perspective View of the burner detached. Fig.5 is a perspective view showing a slightly-modied form of burner. Fig. 6is a perspective View of the burner adapted for use with the ironillustrated in Fig.

Referring to the drawings, the numeral 1 indicates the body of the iron,which is hollow and preferably formed in the usual and well-known shapeand is provided at or near its bottom with a series of air-inletopenings 2.

In carrying out my invention I provide the iron with an opening 3 in itsrear wall 4, in which is inserted a burner 5, which I preferablyconstruct in a single piece, approximately rectangular in form, butprovided with inclined lower edges 5, having therein gasopenings 6, soarranged with relation to the bottom of the iron and inlet-openings 2that a complete admixture of the air and gas will be effected as the airis drawn in through said openings 2, and thus a more regular and uniformheating of the pressing-surface of the iron will be obtained.

Preferably integral with the burner is provided an upwardly-extendingear 7, having therein a vertical slot 8, adapted to register with asimilar slot 9 in a downwardly-extending ear 10, preferably integralwith 'the top plate 11 of the iron.

The numeral l2 indicates a bolt which I prefer to employ and adapted topass through the ears 7 and 10 and a narrow slot lOin the rear wall ofthe iron-and is adapted to hold said burner to the body of the iron andto permit a vertical adjustment of said burner when desired and also tohold the rear end of the top plate in place upon the body of the iron,the front end of said plate being held in position by a set-screw. Inthe forward end of the burner, to the under side thereof, is anadjusting-screw 13, which has its lower end resting, preferably, on thefloor 0f the iron, a1- though, if found desirable, it may be made torest on a lug or other suitable means secured within said iron-body, asis evident.

The numeral 14 indicates an ordinary joint or connection, preferablyscrewed into the rear end of the burner 5, as shown, and adapted toreceive a short vertical pipe 15, provided with perforations 1G foradmission of air to mix with the gas as it passes to the burner in theiron, and a stop-cock 17, adapted to receive on one end thereof theusual iiexible tubing, (not shown,) asis common in this class ofgas-fittings.

Interposed between the iron-bod y l and the top plate 11 is a plate ofasbestos or` other heatnon-conducting material 1S to prevent the heatfrom the iron reaching the handle. I preferably provide the `top plate11` with standards 19, provided near their upper ends with open slots 2Oto receive the rod 21 of the handle and permit a vertical adjustment ofthe same. In order that the heat from the iron be prevented reaching thehandle 22, I

preferably provide'asbcstos washers 23, in-

terposed between the wooden portion of the handle and the metallicstandards 19.

Referring particularly to Fig. 5 and Fig. 6, the numeral 24 indicates aburner formed with a mixing-chamber 25, provided with aninternally-screw-threaded aperture 26 for the reception of a pipe 27,similar to the pipe 15 just described. In order that this burner may bevertically adjustable I provide an ear 28, preferably cast integral withthe mixing-chamber 25 and adapted to be heldin contact with a dependingear 10 on the top plate of the irony by the bolt 12. As a further meansfor securing this form of burner rigidly in the body of the iron Ipreferably provide a short lateral extension 29, having therein an openslot 30 to receive a screw 31, which, in conjunction with the bolt 12,serves tohold the burner in desired adj usted position. It will beobserved that the body and top plate of the iron shown in Fig. 5 are'thesame as those shown in Fig. 1.

I preferably extend the plate 11 of the iron considerably beyond oneside wall of the chamber, and the said wall of said chamber ispreferably cut away, as indicated by the numeral 32, to permit theescape ofv heat, which will be deflected by lthis lateral eXtension ofthe plate 11 for the obvious purpose of preventing the heat fromreaching the hand of the user. In order to increase the heatingsurfaceof the iron, I preferably, though not necessarily, corrugate the iloorof the iron, as shown by the numeral 33.

In irons of this general character it is highly important that a perfectadmixture of the air and gas be effected, and with this object in view Ipreferably provide the burner 5 with the openings 6 opposite theperforations 2, so that the air in coming through said perforations willbe brought in contact with the obliquely-projected flame from theburner, thus producing perfect combustion and preventing the smutting ofthe bottom of the iron adjacent to the burner.

Minor modifications involving mechanical skill may be made Withoutdeparting from the spirit of the invention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. In a gas-heated iiat-iron, the combination with a hollow bodyprovided with airinlet openings near the bottom thereof, and arectangular opening in its rear wall, of a burner in said body of lesssize than the opening in the rear wall and provided with a slotted ear,a top plate provided with a slotted ear adapted to register with the earon the burner, and means for locking the two ears and body together,whereby the top plate is held to the body and the burner locked in anyadjusted position with relation to the bottom of the body, substantiallyas described.

2. In a gas-heated fiat-iron, the combination with a hollow bodyprovided with airinlet openings near the bottom thereof, and arectangular opening lin its rear wall, of a burner in said body of lesssize than the opening in the rear walland provided with an ear, a topplate provided with an ear adapted to register with the ear on theburner, and means for locking the two ears and bod.)7 together, wherebythe top plate is held to the body and the burner locked in any adjustedposition with relation to the bottom of the body, substantially asdescribed.

3. In a gas-heated fiat-iron, the combination with a hollow bodyprovided with airinlet openings near the bottom thereof, and arectangular opening in its rear wall and a narrow slot also in saidwall, a burner in said body of less size than the rectangular openingand provided with a slotted ear, a top plate provided with a slotted earadapted to register with the ear on the burner and with the slot in therear wall of the body, a bolt passing through the slots in the ears andthe slot in the body, whereby the top plate is held to the body and theburner locked in any adjusted position with relation to the bottom ofthe body, substantially as described.

4. In a gas-heated flat-iron, the combination with a hollow bodyprovided with airinlet openings near the bottom thereof, and arectangular opening in its rear wall, of a burner in said body of lesssize than said opening and provided with a slotted ear 28, and also witha slotted ear or lateral extension 29, a top plate provided with aslotted ear adapted to register with the ear 28 on the burner, means forlocking the ears 10 and 2S'I to the body, and means for locking the earor lateral extension to the body, whereby the top plate is held to thebody and the burnerlocked in any adjusted position with relation to thebottom of the iron, substantially as described.

In testimony whereof I affix my signaturex in presence of two witnesses.y
